If you don't like masks, don't wear one or look at those who do. There are lots of reasons cd's wear masks. Some prefer to have beards in guy mode but like to occasionally like to dress up and want to see their mirror reflection as something more feminine-looking than a bearded guy in a dress.
I wouldn't be caught dead in an ankle-length skirt or dress. It just doesn't do it for me. I may not even understand why anyone (gg or cd) would want to wear one. But I don't have to understand it in order to accept the idea that others like it. We all dress the way we do for our own reasons. So let's give the mask wearers a break.
